[PJC]
Cannabis Indica, the Indian hemp, now considered a variety
of the common hemp ({Cannabis sativa), originating in
Asia but now grown widely around the world. It can be
formed into a tough fiber that is used to make rope and
tough fabric. The dried leaves and female flowers are
smoked or chewed by people to produce a euphoric or
hallucinogenic effect, caused mainly by the substance
tetrahydrocannabinol (THC) contained in it. The
THC-containing products of Cannabis are classified as a
controlled substance, and posession and sale are illegal
in most states of the United States. Once classified as a
narcotic, the plant is now more commonly referred to in
the category of euphoric or hallucinogenic agents.
